Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a locking device for a glove box of an automobile, etc., which is opened and closed by pushing an operating piece.

(Prior Art) Conventionally, there is a glove box locking device of this type as shown in Japanese Utility Model Publication No. 57-37817. That is, as shown in FIG. 5, the glove box locking device attached to the opening/closing lid of the glove box locks the proximal end 15a of the hook 15 which engages with the box side striker 14 by pushing the operating piece 13. An opening/closing mechanism that swings the hook 15 to disengage it from the striker 14 when pushed in, and a cylinder lock rotor 16 in the locked position.
A locking mechanism is integrally incorporated in the locking mechanism in which the outer circumferential protrusion 16a engages with the engagement piece of the operating piece 13 and makes it impossible to push the operating piece 13.

(Problem to be solved by the invention) However, in the hook type shown in Fig. 5, the center part of the hook is pivotally supported by the lock body, the tip hook part engages with the striker, and the hook part at the other end engages with the striker. Since the end is biased by a coiled spring so that it comes into contact with the operating piece, in the event of a vehicle collision, a rotational moment is generated by the hook's own weight, causing the hook to rotate and disengage from the striker. The sex was hot.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems, and includes a substantially L-shaped swinging lever that is pivotally supported on the main body of the glove box. The lock slider can be moved by pushing the operation piece by touching one end of the operation piece protrusion embedded in the operation piece and the other end contacting the pin installed on the lock slider that moves up and down perpendicular to the pushing direction of the operation piece. At the same time, the locking piece of the cylinder lock rotor arranged adjacent to the operating piece comes into contact with the lower end of the operating piece in the locked position, preventing the operating piece from being pushed in. It was designed to prevent them from getting it.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. The glove box locking device is attached to the opening/closing lid of the glove box of a vehicle, and includes a main body case (described later) provided on the front side of the opening/closing lid, and a lock slider (described below) that engages with a striker in the glove box provided on the back side. It is integrally formed with a lock slider case that houses the lock slider case.

1 shows the main body case of the glove box locking device, and inside the main body case 1 there is a box-shaped operating piece 2.
is internally slidable in the horizontal axis direction.

A substantially L-shaped swinging lever 3 is pivotally supported on the back plate 1a of the main body case 1 via a support shaft 4, and one end 3a of the swinging lever 3 is installed on the back of the operating piece 2. The other end 3b moves up and down perpendicular to the pushing direction of the operating piece 2, and is inserted into the lock slider case 6 fixed to the rear side of the main body case 1 by a biasing spring. A certain return spring 7
The lock slider 8 is brought into contact with pins 8a installed on the front surface of the lock slider 8, which is internally movable up and down through the lock slider 8.
is moved downward against the return spring 7.

The back plate 1a of the main body case 1 is provided with a horizontally long elongated hole 9 having a length sufficient to allow the operation piece protrusion 5 to slide in the horizontal axis direction when the operation piece 2 is pressed. The front surface of the slider case 6 is provided with a vertically long hole 10 having a length sufficient to allow the pin 8a to slide in the vertical axis direction due to the vertical movement of the lock slider 8.
are perforated, respectively, making the above-mentioned configuration possible.

Further, a cylindrical lock case 11 is formed from the approximate center to the back of the main body case 1, and inside the cylinder lock case 11 is a rotor 12 having a locking piece 12a at its outer peripheral end. The interior is rotatable. In this way, the locking piece 12a of the cylinder lock rotor 12, which is arranged adjacent to the operating piece 2, prevents the operating piece 2 from moving when the cylinder lock is in the locked position.
This makes it impossible to press the operation piece 2.

Reference numeral 17 shown in FIG. 1 indicates a striker receiving portion, and a backlash prevention spring 18 is disposed between the striker receiving portion 17 and the back surface of the lock slider 8, and the spring 18 originates from the top of the lock slider case 6.
As a result, when the lock slider 8 and the striker 19 on the box side are engaged, the striker 19 is pressed toward the back surface of the lock slider 8.

Next, the operation of this embodiment will be explained.

When the cylinder lock is in the unlocked state (Fig. 4),
When the operating piece 2 is pushed, the operating piece protrusion 5 slides in the horizontal axis direction within the elongated hole 9, and this sliding pushes one end 3a of the swinging lever 3 to the left in FIG.
As a result, the swing lever 3 rotates counterclockwise in FIG. 1 about the support shaft 4, and the other end 3b of the swing lever 3 moves downward. As a result, the lock slider 8 moves downward, and the lock slider 8 is disengaged from the striker 19 inside the box, allowing the lid to be opened.

Next, when the cylinder lock is in the locked state (FIG. 4), the locking piece 12a of the cylinder lock rotor 12 comes into contact with the lower end of the operating piece 2. This restricts the leftward sliding of the operating piece 2, and even if the operating piece 2 is pushed, the operating piece 2 cannot be pushed in, making it impossible to open the lid.

(Effects of the invention) The present invention replaces the hook that engages with the striker of the locking device of a glove box of the type that opens by pushing the operation piece with a slider as described above. Also, there is an excellent effect that the slider does not slide even in the event of a collision, and the engagement between the lid and the striker does not easily come loose.

Claims (1)

[Scope of utility model registration request] The opening/closing mechanism is attached to the opening/closing lid, and in the unlocked state, the engaging member is actuated by pressing the operating piece, and the engaging member is disengaged from the box side striker to enable the lid to be opened. In a glove box locking device provided with a locking mechanism that cannot be pushed in and cannot be opened, a substantially L-shaped swinging lever is pivotally supported on the main body of the glove box locking device, One end of the swing lever is brought into contact with an operation piece protrusion embedded in the operation piece, and the other end is brought into contact with a pin installed on a lock slider that moves up and down orthogonally to the pushing direction of the operation piece, thereby pushing the operation piece. When operated, the lock slider is moved downward against the biasing spring, and the locking piece of the cylinder lock rotor, which is placed adjacent to the operating piece, comes into contact with the lower end of the operating piece in the locked position, causing the pushing of the operating piece. A locking device for a glove box, characterized in that a locking operation cannot be performed.
